Yup, well done!
This would have been my next clue:

Daniel Radcliffe starred in the 2012 remake as the unfortunate young lawyer; this is the TV movie from 1989. The guy in the first picture is Bernard Hepton as the local farming magnate who helps the hero; Hepton starred in
Secret Army, a brilliant drama about the Belgian Resistance that has unfortunately been overshadowed by its parody,
'Allo 'Allo! (He's also, I've just learned, in
Get Carter.)
